Furthermore, I would suggest that no horse or cattle slaughterer, tallow-melter, manure-merchant, tanner, or other person plying any of the trades known as noisome or offensive, should be allowed to continue such trades without a special licence, and that by the terms of such licence they should be prohibited, under heavy penalties, from carrying on their businesses outside the limits of a certain area to be expressly set aside for that purpose, at such a distance from the centre of every town as may be judged desirable by the sanitary authorities. Within this area pig-styes and fowl-houses should be erected, and no swine, ducks, or geese be permitted to be kept outside its boundary. An inspector should be appointed specially for this quarter of the town, who should direct all his energies to seeing that the best principles of ventilation, smoke-consumption, drainage, use of disinfectants, &c. &c., are adopted throughout his domain; and all ill-conditioned recusants against the decrees of the local senate should be mulcted in heavy damages. On the part of the senate itself there must be no apathy, no supineness, no dilettanteism, but a stern, vigorous determination stringently and impartially to enforce prompt obedience to its edicts. No doubt this would be somewhat of a hardship upon certain individuals, on the score of inconvenience and increased cost of production; but I doubt not they would take care to indemnify themselves. Even were it otherwise, however, the aggregate gain in so important a matter as the public health must swamp all minor considerations. Private interests must inevitably be sacrificed in the advancement of the general weal. All the Mrs. Partingtons that ever existed, with all their mops (whether such mops are called monopolies, vested rights, or what not), must perforce recede before the rising tide of the ocean of civilization. Having well drained our streets and habitations, and consecrated a _quartier_ for the purposes last mentioned, the next step must be to increase the number of our iron hospitals; and, disregarding sentimentality, immediately to isolate and put in quarantine all persons suffering from infectious diseases. Firmly grasp this nettle the moment it crops up, and without a shadow of doubt you will reduce to a minimum the high rate of mortality at present existing in our overcrowded cities through a total neglect of proper precaution. All textile fabrics, bedding, books, &c., which have come in contact with the patient, to be consumed by fire. Even Vandalism is excusable, nay, commendable, in certain circumstances. Finally, on this branch of the subject, I submit for the consideration of municipalities the following recommendations:--
